All Jammed Up, DOT Urgently Seeks Complementary PNT
For years, the U.S. Department of Transportation (DOT) has been exploring the technologies and systems necessary to provide positioning, navigation, and timing (PNT) services to complement the Global Positioning System (GPS) so that these critical services remain available even when GPS signals are disrupted. In the past few months, the department has ramped up these Complementary PNT (CPNT) efforts, from its issuance of a CPNT Action Plan in September to a related Request for Information (RFI) seeking industry input on CPNT technologies. What are these efforts, how are they going and why the sense of urgency now? The DOT’s CPNT Action Plan, issued this September, provides a comprehensive roadmap to ensure the safety, security, and efficiency of critical infrastructure in the face of potential GPS disruptions through the adoption of CPNT technologies.
Stakeholder engagement across the PNT enterprise, including providers of PNT services and critical infrastructure owners and operators, ranks high among the plan’s key strategies and actions. So does the development of CPNT solutions specifications and standards. The plan further includes a goal of establishing field trials and test ranges to evaluate the performance and resilience of domain-specific (e.g., maritime, rail, and surface applications) CPNT technologies, based on quantitative performance metrics.
